Hi Leticia,
I have only imported a few Sketch-Up files, mostly whole building shells. I used the Merge import method for those. The resulting ‘object’ looks great and seem fairly small in poly count. However, I prefer not to use them for precision modeling work, only general visualization.
For interior objects, I try to find well-made objects and sometimes convert them. In cases of items with high poly counts (e.g., furnishings and equipment), I prefer to create those items anew in AC using the morph tool. Then they are native with fewer polys.
